Definitions

  • the present invention relates to stuffing of flowable product into casing lengths, such as cellulosic food casing, conventionally used to make sausages and other similar products. More particularly, the present invention relates to an improved stuffing apparatus for use especially in conjunction with controllably premoisturized, shirred casing.
  • stuffing apparatus is commonly used in the food industry, for example, to automatically stuff food product, e.g., meat emulsion, into a casing length deshirred from a shirred casing supply mounted over a stuffing horn. After the product is stuffed, the casing is constricted and gathered around the end of the stuffed product by closing a pair of gathering plates. The stuffed product is then closed by applying a clip around the gathered end of the casing.
  • food product e.g., meat emulsion
  • the casing since the moisture content of the casing is maintained at a controlled level, the casing tends to behave in a predictable fashion on the stuffing apparatus. Finally, since soaking is no longer a requirement, the casing can be shirred to higher pack ratios so that a greater length of casing can be shirred onto a stick of predetermined length. It will be readily apparent that this feature significantly reduces the apparatus downtime due to stick loading.
  • a commercially acceptable level e.g., from about 15.5% to about 35%, and preferably to about 20%, of total casing weight
  • the tension sleeve is connected at its other end to a reciprocating mechanism which cycles the tension sleeve first aft, then fore, to create a controlled length of slack casing which, in effect, substantially reduces the holdback force developed in the casing supply during gathering.
  • the slack casing so provided is thus available to be drawn by the gathering plates around the end of the stuffed product.
  • US-A-3,748,690 to Niedecker discloses a stuffing apparatus for stuffing sausage casings and the like wherein the stuffing horn is provided with a snubbing ring adjacent to its discharge end.
  • the snubbing ring is arranged to reduce the casing holdback immediately after completion of the filling operation in order to accommodate flowable product that is displaced during the constriction and gathering operation.
  • DE-A-32 21 923 discloses an improved stuffing method and apparatus which is primarily adapted to the utilization of controllably premoisturized casing.
  • a tension sleeve carrying a sizing disc or ring is provided along with a snubbing ring mounted adjacent to the discharge end of the stuffing horn.
  • the snubbing ring serves infold the stretched casing as it passes from around the sizing disc or ring and also provides an emulsion seal as the infolded casing passes between the snubbing ring and stuffing horn.
  • the tension sleeve is adapted to reciprocate in order to provide slack in the casing while the snubbing ring is maintained in fixed or stationary position.
  • BE-A-895 031 discloses an apparatus for stuffing a flowable product into continuous length of controllably premoistured tubular casing.
  • a sizing member is disposed within an unshirred portion of the shirred casing supply and having an outer circumference which contacts the inner surface of the casing for stretching the casing to a predetermined dimension.
  • a sealing member cooperating with the sizing member is a sealing member surrounding the stuffing horn and contacting the outer surface of the stretched unshirred casing for folding the casing inwardly as it is drawn around and over the sizing member.
  • the sealing member is controllably movable along the stuffing horn from a position adjacent to the sizing member to a position adjacent to the discharge end of the stuffing horn in order to change the holdback force of the casing from a maximum in the position of the sealing member adjacent to the sizing member and a minimum in the position of the sealing member adjacent to the discharge end of the stuffing horn. Since both, the sizing member and the sealing member, have relatively large cylindrical surface contact areas, the decrease of the casing contact surface area upon moving the sealing member is relatively small and the change of the holdback force will be low.
  • the present invention contemplates a further improvement for stuffing a flowable product into continuous length of controllably premoistured tubular casing by reducing the surface contact area of the sizing member in relationship to the surface contact area of the engaging member, so that moving of the engaging member will influence the increase resp. decrease of the holdback force in a substantially manner. According to the present invention this will be achieved by an apparatus according to claim 1 and a casing article according to claim 17.
  • the stuffing operation according to the present invention is carried out by mounting within the interior of the tubular casing a sizing member having an outer circumference which is larger than the casing in its initial unstuffed condition and then drawing the tubular casing over the sizing member in order to stretch the casing to about its recommended stuffed circumference.
  • the outer circumference of the sizing member is provided with a casing contact surface area which is relatively small and which consequently reduces the force (i.e. holdback force) required to pull the casing over the sizing member.
  • An engaging member or snubbing ring is placed around the exterior of the tubular casing in order to infold the stretched, deshirred casing after it has been drawn over the sizing member.
  • the engaging member holds the casing against the surface of the stuffing horn to provide an emulsion seal. Further, the engaging member has an arcuate projection or extended lip which coacts with the sizing member to force the casing to follow a convoluted path. This, in turn, creates a high frictional holdback force on the casing. This holdback force, together with the holdback force created by the stretching action of the sizing member, combine to provide a total holdback force sufficient to control or regulate the internal stuffing pressure, thereby insuring that the casing will stuff out to the desired stuffed circumference.
  • the engaging member is positioned in close proximity to the sizing member which is mounted inside the casing. However, said engaging member is caused to move longitudinally along the length of the stuffing horn just prior to or during the stuffed product gathering and clipping step, from its initial position adjacent to the sizing member to a point proximate to the discharge end of the stuffing horn. This substantially reduces the casing holdback force and thereby allows the casing to be drawn on demand from the shirred casing supply during the stuffed product gathering and clipping step.
  • the internal sizing member is held fixed or stationary throughout the entire stuffing, gathering and clipping operation. This is made possible by the fact that the sizing member generally does not apply the major portion of the holdback force against the casing during the stretching operation. Accordingly, since the sizing member is fixed or stationary, essentially all of the space available to store the shirred casing on the stuffing horn can be readily utilized without sacrificing any space to accommodate reciprocating movement of a tension sleeve of similar device for supporting the sizing member:
  • the shirred casing supply used with the preferred embodiment may comprise a "cored high density" casing stick as described in DE-A-32 16 011 incorporated herein by reference.
  • a cored high density casing article comprises a support tube or tubular core member with a shirred casing length mounted thereon and highly compacted to a high pack ratio (at least about 100) and a high packing efficiency (at least about 0.50).
  • Such a configuration provides a casing article having improved structural stability and strength, and it supplies additional stuffing length as compared to conventional shirred sticks.
  • the present invention comprehends a casing article comprising in combination, an elongated tubular core member having affixed thereto at one end a conically shaped sizing member, and a continuous length of a controllably premoistured tubular casing shirred and compacted over substantially the entire length of said tubular core member, said conically shaped sizing member being disposed within an unshirred portion of said casing and having an outer periphery of substantially fixed circumference which is larger than the interior circumference of said casing, such that said casing is stretched outwardly when the casing is drawn around and over said periphery, said periphery having a casing contact surface area which produces a minimal holdback force on the casing so that the casing can be drawn easily around and over the periphery of the sizing member when no other holdback forces are applied thereto.
  • the internal sizing member is preferably conical in shape as opposed to a cylindrical disc and is, preferably, made integral with the outer end of the tubular core member.
  • This sizing member can be conveniently made by molding the sizing member in one piece with the tubular core member. Since the sizing member must stretch the casing, it must be made of a substantially unresilient material such as metal or, preferably, a rigid plastic such as high density polyethylene.
  • the engaging member preferably includes an annular projection which surrounds the inner circumference thereof and can coact with the internal sizing member to create a convoluted casing path.
  • the annular projection on the engaging member is adapted to enter the open annular space defined between the conical sizing member and the stuffing horn. This arrangement is utilized to effectively increase the convolution of the casing passage and thereby produces a significant portion of the holdback force to control or regulate the internal stuffing pressure.
  • FIG. 1 and 2 there is shown in Figures 1 and 2 an apparatus according to the present invention for stuffing a flowable product such as a meat emulsion 10 into continuous lengths of tubular cellulosic casing 12.
  • the casing 12 is a controllably premoisturized casing which is shirred and compacted tightly onto an elongated plastic tube or core 14 to form a complete casing article depicted generally by the reference numeral 16.
  • the casing article 16 is loaded onto the stuffing apparatus by placing the plastic tube or core 14 over the elongated stuffing horn 18. Only those parts of the stuffing apparatus are shown that are considered essential to an understanding of the present invention.
  • the casing article 16 is detachably mounted onto the apparatus by means of a pair of mounting plates 20, 22. These mounting plates each have coinciding openings through which passes the aft end of the stuffing horn 18.
  • the outermost plate 22 is fixed to a part of the apparatus, not shown, while the other innermost plate 20 is removably secured thereto as by set screws, also not shown.
  • the innermost plate 20 carries around the periphery of its opening an interrupted flange element 24 which forms part of a conventional bayonet mount arrangement.
  • the inboard end of the plastic tube or core 14 is formed with similar spaced interrupted flange elements as at 26 which engage the flange element 24 and detachably lock the tube in place upon rotation.
  • a conically shaped sizing member 28 is disposed within the interior of the tubular casing 12.
  • the sizing member 28 is affixed to the fore end of the elongated plastic tube or core 14 and preferably, though not necessarily, is made an integral part thereof.
  • the sizing member 28 is molded in one piece with the plastic tube or core 14.
  • the sizing member 28 can be made as a separate piece and then suitably secured onto the end of the plastic tube or core 14.
  • the sizing member 28 can also be detachably secured by suitable means to the stuffing horn if desired.
  • the conically shaped sizing member 28 in its preferred form includes an outwardly flared wall 30 terminating at its outer edge in a narrow, rounded peripheral rim 32.
  • the wall 30 is disposed at an angle 0 with respect to the longitudinal axis of the plastic tube or core 14 defining an open annular space 34 between the wall 30 and the outer surface of the stuffing horn 18.
  • the elongated plastic tube or core 14 is preferably made as long as possible in order to incorporate the maximum length of shirred tubular casing within the casing article 16. However, the plastic tube or core 14 is shorter than the overall length of the stuffing horn 18 leaving a part of the latter exposed in an area adjacent to the discharge end 36.
  • a snubbing ring or engaging member 38 is disposed concentrically around the exposed area on the stuffing horn 18.
  • the engaging member 38 contacts the exterior surface of the stretched, unshirred casing 12 and infolds the casing as it is drawn from around the outer rim 32 of the sizing member 28.
  • the engaging member 38 is formed around its inner periphery with an annular, arcuate shaped projection 40.
  • the annular projection 40 contacts the exterior surface of the stretched, unshirred casing 12 and, in concert with the sizing member 28, produces a holdback force on the casing.
  • the inner periphery of the engaging member 38 also holds the casing 12 snugly around the discharge end 36 of the stuffing horn 18. This prevents back flow of the meat emulsion extruded from the stuffing horn 18, that is, the engaging member prevents the meat emulsion from entering the casing 12 at a point inboard of the engaging member 38.
  • the outer periphery of the engaging member 38 is secured inside an annular groove 42 formed on the inner surface of a circular carriage 44.
  • This carriage 44 is connected to a suitable drive mechanism, not shown, which is adapted to move the carriage 44 and engaging member 38 longitudinally along the exposed area on the stuffing horn 18 in both the fore and aft direction as depicted by the arrows.
  • the mechanism for driving the carriage 44 may be, for example, a pair of pneumatic cylinders operating in tandem or any similar device.
  • the meat emulsion 10 extrudes from the discharge end 36 of the stuffing horn 18 under pressure from an emulsion pump, not shown, the meat emulsion fills the tubular casing 12 outwardly to the desired stuffing circumference.
  • the casing 12 is continuously deshirred from the casing article 16 and is drawn over the peripheral rim 32 of the sizing member 28.
  • the rim 32 stretches the casing outwardly to about its recommended stuff diameter and thereby reduces the internal pressure required to complete the stuffing operation.
  • the stretched casing 12 is then infolded and continuously drawn around the arcuate annular projection or extended lip 40 of engaging member 38.
  • the ring 38 contacts the casing and holds it snugly against the surface of the stuffing horn 18.
  • the engaging member 38 is positioned adjacent to the conically shaped sizing member 28 as illustrated in the view of Figure 1.
  • the extended lip 40 is placed inside the annular space 34 between the flared wall 30 and the stuffing horn 18.
  • a pair of constriction plates 46, 48 are located just ahead of the discharge end 36 of the stuffing horn 18. These plates simultaneously close together to constrict the filled casing 12 as shown in the view of Figure 2.
  • the extra casing required to form the rear or trailing end of the just-stuffed product length and the front end of the succeeding "next-to-be-stuffed" product length is pulled from the shirred casing supply, and over the sizing member, by the action of the constriction plates.
  • a pair of clips (not shown) seal the rear end of the just-stuffed product length and the front end of the next product length, and a severing means (not shown) separates the casing between the clips.
  • the engaging member 38 is withdrawn from horn discharge end 36 and positioned again .adjacent to the conically shaped sizing member 28. Emulsion flow is reactivated, and stuffing of the next product length commences.
  • the rim 32 formed by the outer periphery of the sizing member 28 has a relatively small surface area which contacts the interior of the casing 12. While stretching the casing 12 to about its recommended stuffing circumference, said sizing member, therefore, produces a minimal holdback force on the casing. When in the constriction and gathering position shown in Figure 2, the major portion of the total holdback force which is acting on the casing becomes that portion which is due to this stretching contact of the sizing member. This allows the constricting and gathering action to easily draw casing from the shirred casing supply over the rim 32 as required. There is, therefore, no necessity to move or reciprocate the casing supply 16 to create slack during the constriction, gathering and clipping operation. It is only necessary to move the engaging member 38 approximately 3/8-inch away from the sizing member 28 to eliminate a substantial portion of the total holdback force on the casing.
  • a mounting plate adjustment mechanism 50 This mechanism may consist, for example, of a rotatable knob 52 having a tubular extension 54 mounted on a stationary shaft 56.
  • the tubular extension 54 is threadably engaged inside a tubular sleeve 58 which in turn is fixedly secured in an opening 60 formed within the mounting plate 22. It will be seen then that by simply rotating the knob 52 either clockwise or counterclockwise, the plate 22 and, in turn, the tube or core 14 can be moved, in small increments, longitudinally in either direction along the length of the stuffing horn 18.
  • This movement of the tube or core 14 causes the conically shaped sizing member 28 to relocate either closer to or farther from the engaging member 38 and its projection 40, thereby controlling the amount of total holdback to be developed in the casing supply.
  • provision is thereby made to assure that an optimum portion of the casing contact surface area on the arcuate annular projection 40 will be in contact with the infolded casing during stuffing in order to provide that the. total holdback force will produce the desired stuffed casing circumference or diameter.
  • the mechanism whereby the level of holdback contributed by the engaging member 38 is controlled involves the amount of casing 12 which is wrapped around arcuate projection 40 as the casing moves over the sizing member 28 and past the engaging member.
  • the angle 0 defined between the flared wall 30 and the longitudinal axis of the plastic tube or core 14 may be any angle in a range of between about 30 and 75 degrees, for example.
  • the angle O is about 45°. This preferred angle provides a space 34 for creating casing holdback.
  • FIG. 3 An alternate and preferred assembly for detachably mounting the casing article on the stuffing apparatus and adjusting the longitudinal position of tube or core 14 is shown in Figure 3.
  • An internally threaded outer ring 62 provided with openings 64 about its periphery, is mounted concentric to the stuffing horn 18 and. bolted to the horn attachment nut 66 of the stuffing apparatus.
  • An externally threaded adjusting ring 60 is concentrically mounted around the stuffing horn and threadably engaged within outer ring 62.
  • a number of adjusting holes 70 are radially bored around the periphery of the adjusting ring so that they are accessible through the openings 64 of outer ring 62 for the insertion of a rod (not shown) into a hole 70 for adjusting the position of ring 60 within ring 62 by rotating ring 60.
  • An adapter ring 72 is, in turn, mounted concentric to the stuffing horn and bolted to the face 74 of adjusting ring 60.
  • the adapter ring carries around the periphery of its opening 76 an interrupted flange element 78 which forms part of a conventional bayonet mount arrangement. Only the adapter ring 72 need be changed to accommodate different tubular core inboard sizes.
  • the inboard end of the plastic tube or core 14 of the casing article is formed with a similar spaced interrupted flange element which engages the flange element 78 and detachably locks the tube in place upon rotation. It will be seen that by simply rotating the externally threaded adjusting ring 60, within the internally threaded outer ring 62, the adapter ring 72 and, in turn, the tube or core 14 of the casing article can be moved longitudinally in either direction along the stuffing horn 18, establishing any desired relationship between the sizing member 28 and the engaging member 38.
  • the internal sizing member could have a convoluted outer periphery which would impart little or no pre- stretching or holdback to the casing until an engaging member, provided with a plurality of fingers or protuberances, pressed and stretched the casing into the recessed portions of the convoluted sizing member.
  • the internal sizing member can have a shape (e.g. ellipsoidal, hemispherical, etc.) other than a conical shape, as long as an annular space is provided between said sizing member and the stuffing horn to allow coaction with the engaging member, and provided that the contact area of the sizing member with the casing is roughly equivalent to that provided by the rim of a conical sizing member.
  • a shape e.g. ellipsoidal, hemispherical, etc.
